SYLVESTER F. NEWLAND, OF WAYNESFIELD, OHIO, ASSIGNOR TO HIMSELF ANDRUFUS I. KREBS, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 227,819, dated May 18,1880.

Application filed March a, 1880. (Model) To all whom it may concern:

Be it known that I, SYLVESTER F. NEW7 LAND, of Waynesfield, in thecounty of Auglaize and State of Ohio, have invented a new and ImprovedOar-Coupler, of which the following is a specification.

Figure 1 is a vertical sectional elevation of the coupler on line yy,Fig. 2. Fig. 2'is a vertical sectional elevation on line so on, Fig. 1.

Fig. 3 is a perspective view of the couplingpin. Fig. 4 is a plan of thecoupling-link.

Similar letters of reference indicate corresponding parts.

This invention relates to that class of coup- I 5 lers calledself-couplers and it consists of a five pronged spring actuatedcouplingpin, which is held and guided between two vertical standardsthat are fixed on top of the drawhead; and it consists, further, of alink of a peculiar construction, as will hereinafter be described.

In the drawings, A represents the drawhead. B B are the verticalstandards fixed on top of the draw-head A, and united at the top by thecross-piece O. D is the coupling-pin,

provided with the shank a, which projects upward through the center ofthe cross-piece O. b is the square shoulder of the coupling-pin D,fitting between the standards B B. c is the 0 main central prong of thecoupling-pin D, which prong c is broad and flat, and terminates in thepoint (I, which enters a socket, f, in the bottom of the drawhead A, onthe inside thereof, the front lower corner of the said prong 3 5 0 beingrounded off, as shown at It, so that the said pin D may be readilylifted by the thrust of the beveled end of the link E. g g represent thefour smaller prongs of the couplingpin D, which prongs g 9 projectdownward 0 from each of the four corners of the said couplin g-pin D. V

The coupling-link E is a flat bar of metal, having in each end anelongated rectangular opening, It, for the reception of the central 5prong, c, of the coupling-pin D. SaidlinkE is flat on the under side,and on its upper face the four grooves m m are formed on either side ofthe rectangular openings 70, said grooves m m being designed for thereception of the ends of the prongs g g of the coupling-pin D. The

ends of the said coupling-link E are beveled, as shown at n, andcentrally grooved, as shown at o, to facilitate the lifting of thecouplingpin D when either end of thelink E enters the draw-head A of thecar.

s is a spiral spring encircling the shank a of the pin D between thecrosspiece O and the shoulder b of the said couplingpin D. r is a socketin the side of said coupling-pin D, in which engages one end of thelever F, which is pivoted in the lugs t, that are attached to one of thestandards B.

G represents the end of the car, on which is pivoted the lever H, oneend of which lever is connected with the shank (t of the couplingpin D.

If the coupling-link E be thrust into the draw-head A, it comes incontact with. the central prong, c, of the coupling-pin D and raises thesaid pin, and as soon as the point of the said link E has passed thepoint cl of the said coupling-pin D the prong c of the pin D is forcedinto the opening lc of thelink by the spring 8 passing through the saidopening 70, so that the point cl shall enter the socketfin the draw-headA, and at the same time the prongs g of the coupling-pin I) engage inthe grooves m of the link E, and in this'mauuer the cars are firmlycoupled. The brakeman may nucouple the cars from the side by means ofthe lever F, or from the top of the car by means of the lever H.

A special advantage of this car-coupler is, that it will automaticallyuncouple, for it will be seen that if the coupling-link E be inclined 85 sidewise at an angleof about forty-five degrees it will, by means ofits upward pressure upon two of the prongs g g, lift the central prong,c, from out of the opening It of the link, so that the cars will beuncoupled at once. Hence it will be seen that if one car should bethrown from the track and tip or incline at an angle of forty-fivedegrees, or thereabout, said car would uncouple from the next car, andby this automatic uncoupling much loss of life and 5 property may besaved.

Having thus described myinvention,Iclaim as new and desire to secure byLetters Pat-- ent--- 1. A car-coupling constructed substantially IOO asherein shown and described, consisting of coupling-pin D, provided withfive downwardprojecting prongs, 0 g g g g, and a couplinglink, E,provided with openings 70, grooves m m, and beveled and grooved ends,all arranged as set forth.

2. In a carcoupler, the combination, with the draw-head A and standardsB B, of the coupling-pin D, provided with shank a, shoulder I), centralprong, 0, and corner prongs g g, substantially as herein shown anddescribed;

3. The combination, with the five-'pronged coupling-pin D, of thecoupling-link E, provided with openings k, side grooves, m, beveled endsat, and endgrooves, 0, substantially as 15 shown and described.
